Reaction to climate deal

Here's some of the reaction from officials and environmental groups to the climate deal announced tonight in Copenhagen:

"President Obama’s hands-on engagement broke through the bickering and sets the stage for a final deal and for Senate passage this spring of major legislation at home. It’s a powerful signal to see President Obama, Premier Wen, Prime Minister Singh, and President Zuma agree on a meeting of the minds. These are the four horsemen of a climate change solution. With this in hand, we can work to pass domestic legislation early next year to bring us across the finish line."

-- US Senator John F. Kerry

"The city of Copenhagen is a climate crime scene tonight, with the guilty men and women fleeing to the airport in shame. World leaders had a once in a generation chance to change the world for good, to avert catastrophic climate change. In the end they produced a poor deal full of loopholes big enough to fly Air Force One through."

-- Kumi Naidoo, executive director of Greenpeace International

"Today's ground-breaking agreement by critical nations is not the end of this process, it is the beginning. It signifies a new era of action where America is willing to be a leader in the fight to combat global warming. This provides an opportunity for the rest of the world to build a comprehensive agreement that so many have been working to achieve for so long."

-- U.S. Representative Edward J. Markey, chairman of the House Select Committee on Energy Independence and Global Warming

"I applaud President Obama for his determination to not let these talks fail, and his success working with China. The deal is incomplete, and we’re not done yet. But at long last all of the top polluters of the world, including the United States and China, are putting numbers on the table to cut pollution in a transparent way.

-- Larry Schweiger, president and chief executive of the National Wildlife Federation

"Climate negotiations in Copenhagen have yielded a sham agreement with no real requirements for any countries. This is not a strong deal or a just one -- it isn’t even a real one. ... The actions it suggests for the rich countries that caused the climate crisis are extraordinarily inadequate. This is a disastrous outcome for people around the world who face increasingly dire impacts from a destabilizing climate."

-- Erich Pica, president of Friends of the Earth U.S.
